Since I updated to the Feb 25 -CURRENT I'm currently running (from mid-Sept, I believe), I see similar. It seems like the ARC has gotten really unwilling to yield, so it grows up in size, and then doesn't let up under pressure. I saw programs being actively used constantly swapping their working set in and out, since they were left with tiny available memory. Hard-slappping vfs.zfs.arc_max down a ways mitigated it enough to get me through the days, but is a pretty gross hackaround... -- Matthew Fuller (MF4839) | fullermd_at_over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.Received on Tue Mar 06 2018 - 17:19:24 UTC
